ifBe it known that I, Ciinsran J. VAND O BEN, a citizen of. the UnitedStates, residing at Yankton, in the county of Yankton and State of SouthDakota, have invented certain 1 16: and useful Im rovcmentsin'Lubricat-.

'ing Qevices, of whic the following is a specification. ,T

My invention relatesto improvements in a journal and its. bearingirrespective of the position in which said journal is placed. a

. A furtherfiob'ect is to provide means for regulatin the ow of oil uponthe 'ournal, so

that the atter'may becoated wit a film of desired'thickness.

. Other object is to have the several parts rchangeable, so that the maybe reaced'gwhen' too badly worn orfurther use. '.Referring.now-to theaccompan ing draw ing";1gure 1 represents a vertica section of in ournalbox, rovidedwith my improved ofth'e inventiom-Fig. .4 bein taken on lineof .5, and 5 eing taken on line V -Vof- I I: 1 designates a journal box,consisting of' a ipillowillogkfl -and a' cap? 4 designates aournaiimosnted in sai .box j 5' ,a' reservoir "communicating withanopefing 6, centrally .arran ed within cap?a3,' sa ttf reservoirbeingpr'ovied with a bev'el ed lower; end 7, held in contactwith thecorresponding upper surface of'packing 8, by -f-stnd-bolts-9,extendingthrough ears 10 on npperlportion of the reservoir and engagmg cap 3.Said ,bolts are provided at their upper terininals with taps 11, wherebythe reservoir is drawn 0' htly into contact with .the packing, and theatter is drawn into contact with the journal 4, some to render the jointbetween the packing and the reservoir I 'proof against the leakage ofoil thcrethrough.

- -The oil within the reservoir is forced outwardly upon the journal bya plunger 12, consisting of a piston-.head 13, and a stem 14, providedat its outer terminal with a handle 15 whereby the lungor may bemanipulated. Stem-14 extend loosely through a yoke 16,

'ivotally secured by rivets '17 toa pair of rackets 18, remo'vablysecured to the outer end of the reservoir by bol s 9 and taps 11.

oil by an expansion spring l9,-interposed between the piston-head 13 andthe yoke 16. When it. is desired to refill the reservoir, the plunger isdrawn outwardly against the spring 19, and tilted to theposition shownin'Fig- 2, so that access may be readily had to said reservoir; V

Access may be had were packing for the purpose of renewing the sa1ne,'byunscrewing ta all and removing thereservolr; f f

in the modified form- Fig. 3,1' desi' ates a journal box; consisting ofa pillow block 2 and'a cap 3; #desi 'n'ates a ournal niounted in saidbox.,' '5 esignates-a reservoir,

having one end arranged n an opening-6 in cap 3"; said'end beingbe'veled as indicatedat 7?. 8* designates resilient i packing interposed-between journal {4 an the "beveled i "75 end 7 9 designates?stildboltsipas the pa This form, like the one'shown in Figs. 1 and 2, forcesthe oil upon the journahthe difier:

ence being that the plunger 12, automatioally adjusts itself, withrespect to the quantity of oil within the reservoir, whereas thescrew-plug 12 must be manually adjusted.

The advantages obtained in providing a force feed lubricant, are: first,that the journal and its hearing will be constantly supplied with 011until the reservoir is em tied.

econd, the device will operate equa ly as well when the journal box isin an inverted position, or fastened to the side of a post, as wheninthe position shown.

Referring now to the modified form shown in Figs-4 and 5, whichillustrate agravityfeed device, I" designates the journal box consistingof a pillow block 2 and a ca 3". 4* designates a journal mounted in said0x, 5? designates -a reservoir communicating willran opening 6*, in cap3* 8 designates packing interposed between journal 4 and the edge of thereservoir. 9 designates studbolts extending through ears 10 on'thereservoir, and entering cap 3*. 112 desig-.
